Sure, here you go.



The reference shot:

And the red one:

I’ve used Adobe Camera Raw 6.3, but you’re more than welcome to do your own test with a different camera and different raw converter. Just out of interest (though I don’t understand what you find wrong with a calibrated PVA monitor) I’ll print a few sheets with a colour laser printer on Monday and redo the test <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='Wink' />

Great, so what we get is the realization that the screen photographed at such magnification levels is very unsharp (what kind of screen is that???An old crappy CFT?) and that to "test"w aht you say you are testing, you need to use a darker grey with black letters to compare in the first place, because through contrast differences we are unable to compare.



Besides that, with your "test" you really only are testing our visual system, not detail in the red channel.. for that, you will need to actually transfer the detail information to a spectrum our eyes can handle in the same way.



Not a test which shows anything, I am afraid.
